product overview

The metal sheath of high-voltage cables is an important component of the cable. When the cable core passes current, a circulating current will be generated on the metal sheath. Poor insulation status of the outer sheath, poor grounding, and incorrect grounding method of the metal sheath can all cause abnormal circulating current in the sheath, which can seriously threaten the safety of cable operation. When there is abnormal circulation in the metal sheath of the cable, it can cause local high temperature loss and heating of the cable insulation, accelerate insulation aging, reduce the service life of the cable, and in severe cases, lead to direct breakdown grounding fault of the cable. Abnormal sheath circulation can also directly affect cable linesThe current carrying capacity generates significant energy loss, wastes energy, and reduces economic benefits.

WINFOSS-W7 protective layer grounding current monitoring device is designed for underground spacesA monitoring product for the safety design of high-voltage cables in the comprehensive power pipe gallery. Equipped with 4 current monitoring channelsWith 3 temperature measurement channels, real-time automated monitoring of sheath grounding current data can be achieved, and the monitoring data can be presented in chartsThe method is visually displayed and can provide warnings and alerts through data analysis, effectively preventing power cable accidents, extending the service life of power cables, ensuring safe and stable operation of power cables, reducing manual workload, and saving operational management costs.
